SPECIFICATION forming part of Letters Patent No. 617,086, dated January 3, 189 9.

Application tiled March 22, 1898. Serial No. 674,881. (No model.)

To all whom zt may concern,.-

Be it known that l, JOHN MITCHELL, a subject of the Queen of Great Brit-ain, residing at Aston, in the county of Staffordshire, England, have invented certain new and useful Improvements in Tobacco-Pipes, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to tobaccdpipes, and has for its object to provide such a pipe constructed so as to be readily cleansed and also a pipe which may be inverted in use.

The invention consists of a tobacco-pipe constructed substantially as hereinafter described, and defined in the claims.

The invention is fully disclosed in the following specification, of which the accompal nying drawing forms a part, in which the separate parts of my improvement are designated by letters of reference, said drawing illustrating in elevation and partly in vertical central section a tobacco-pipe constructed in accordance with this invention.

Referring to the drawing, A represents the bowl of an ordinary tobacco-pipe, which may be formed of any suitable material, such as brier-wood, nieerschaum, and the like, and which may be made in any desired or preferred shape.

The stem is preferably provided with the usual bore a, which communicates with a vertically-arranged channel a', which is formed in the side wall of the bowl and projects therethrough at both the upper and the lower surfaces. Supplemental channels a2, preferably three in number, are arranged in the bottom of the pipe-bowl and lead from the interior thereof to the lower surface.

The bottom of the pipe-bowl is provided with a cap B, suitably secured thereto, which is substantially dish-shaped and provided upon its outer periphery with a horizontal iiange l). The iiange Z) is connected by a vertical Wall with a second annular iiange Z1' of lesser diameter than the flange l) and is so formed as to surround the centraldish-shaped portion b2 of the cap B. The upper face of the portion b2 is provided with a plurality of orifices in alinement with the channels a2, which communicate with the interior of the pipe-bowl. The flange l1 is also provided with an opening in alinement with the passage a'.

Within the dish-shaped portion b2 is arranged an absorbent disk C, which may be formed of anysuitable or desired material or substance suitable for the purpose of absorb ing and retaining nicotine.

The cap B is preferably constructed of t-hin malleable metal, which may be readily stamped into shape.

The bottom cover D is provided with an upwardly-extending flange d, which is to be secured upon the bottom of the pipe-bowl and is constructed With an upwardly-extending.

portion d', which is so arranged as to coincide with the annular flange b of the cap B. In the center of the bottom cover D is arranged a lug d2, which extends upwardly, so yas to bear against the absorbent disk O and retain the same in its seat.

From the above construction it will be seen that a chamber is formed between the cap B and the bottom cover D, which receives the smoke, from which chamber it is drawn through the passage d and into the bore a. When the absorbent disk becomes foul, it is only necessary to remove the bottom cover D, and the absorbent disk may bereplaced by a fresh one and the pipe purified.

A cover A' is suitably hinged over the top of the bowl of the pipe and is provided with means whereby it may be secured in its closed position over the outer end of the pipe. Suitable orifices are provided through the ltop of the cover A to permit of the proper combus= tion of the tobacco in the bowl of the pipe. This construction renders it possible to invert the pipe and smoke it in that position, as preferred by some smokers, and in prac tice a suitable plug a may be inserted in the end of the passage a. The sunken portion of the cap B is roughened to serve as a matchigniter.

IIaving fully described my invention, I claim as new and desire to secure by Letters Patentm l. A tobacco-pipe provided with the usual bore, and having passages communicating with said bore and with the interior of the pipe-bowl, a cap arranged in the bottom of said pipe and having perforations communi'- TOO cating with said passages, and a cover adapted to be secured over said cap and to the bottoni of the pipe-bowl forming a chamber between said cap and cover, into which said passages lead, and an absorbent disk removably secured in said cap, substantially as described.

2. A tobacco-pipe provided with the usual bore, and having passages communicating therewith and with the interior of the pipebowl, an annular dish-shaped cap secured to the bottom of said pipe-bowl and provided with apertures alining with said passages, and a cover secured to the bottom of the pipebowl and forming a chamber with which said passages communicate, an absorbent disk arranged in said cap, a lug upon said cover adapted to bear against said disk and retain the same in place, substantially as described.

A tobacco-pipe provided with the usual bore, and having a longitudinal passage arranged in the side wall of the bowl and projecting through theupper and lower faces thereof and communicating with said bore, a cap secured upon the bottom of said pipebowl and provided with perforations registering With passages communicating with the interior of said bowl, a cover secured upon the bottom of said pi pe-bowl forming a chamber with which all of said passages communicate, and a cover suitably hinged to the top of said pipe-bowl, whereby said pipe may be inverted and said top cover will act as a bottom for said pipe, substantially as described.

In testimony that I claim the foregoing as Inyinvention I have signed my name, in presence the subscribing witnesses, this 15th day 0f February, 1893.
